I think what Pat and I are saying is that everyone focuses on "its different," but I think the only thing that is truly different is the hole's aesthetic difference caused by the trees, and not the shot requirement. Yes, the trees make the whole different; the trees are taller, in a row, etc. If the trees were replaced with a more similar tree to the rest of the course, and the fairway was the exact same width, I don't think people would have the same reaction to the hole and the requirements of the tee shot. The hole is only 346 yards, and if I remember correctly, opens a little after hitting through the chute of trees.
I believe the tee shot on the 16th is much more difficult with the combination of the baranca, the out of bounds and the gentle dog-leg making the landing area blind. However, because the hole feels a bit more like the rest of the course, everyone sings a different tune.
